From 8758c885c43859266e45db588b1a5992c049c595 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sun, 6 Jan 2013 11:10:38 +0100 Subject: ARM: Kirkwood: Use fixed-regulator instead of board gpio call With the change to a DT based pinctrl/gpio driver, using gpio API calls in board-*.c files no longer works, a dereferenced NULL pointer exception occurs instead. By converting the GPIO code into a fixed-regulator which gets probed later once pinctrl/gpio is available, we avoid the exception.
